Kernel version vs da Capo (batik) benchmark

kernel-benchmark.md

#Kernel Benchmark Use an off the shelf benchmark to test impact of different kernels on benchmark performance. I chose http://www.dacapobench.org/

times=10
f=$(/usr/bin/uname -r)
jdk1.8.0_77/bin/java -jar dacapo-9.12-bach.jar batik -n ${times} > ${f}.txt 2>&1

now run it

then reboot it with a different kernel e.g. upgraded to fix the cpu bug:

-rw-rw-r--.  1 dmo  dmo  3.6K Jan  8 11:16 3.10.0-693.11.6.el7.x86_64.txt
-rw-rw-r--.  1 dmo  dmo  3.6K Jan  8 11:18 3.10.0-693.11.1.el7.x86_64.txt

Now you have a file with all the output of the test.

Extract the "completed" lines:

$ grep completed *.txt

Now convert that into a csv:
